The solution is Option A.
The equation which has a constant of proportionality k = 7 is 4y = 28x
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the equation be represented as A
Now , the value of A is
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
Now , the equation is
4y = 28x
On simplifying the equation , we get
Divide by 4 on both sides of the equation , we get
y = 28x/4
y = 7x
y = 7x is of the form y = kx where the value of k is 7
Therefore, the value of k is 7
Hence , the value of proportionality constant is 7

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.
Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.
Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.
Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.

Answer:
12 sales
Step-by-step explanation:
Let x represent the number of sales each man had.
For Salesman A, he earns $65 per sale; this is 65x.
For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.
Since their pay was equal, set the two expressions equal:
65x = 40x+300
Subtract 40x from each side:
65x-40x = 40x+300-40x
25x = 300
Divide both sides by 25:
25x/25 = 300/25
x = 12

Answer:
Step-by-step explanation:
Since this is a test, I'll give a hint:
To find a missing side, you would ussualy use the pythagoream theory, which is not only a pain to write, but pretty easy!
The formula is a^2+b^2=c^2
a and b are the "legs" (the shorter sides) and c is the hypotonus(the longest side).
In this case a=x, and b=6. C=10.
Just input a, b, and c into the equation, and if you have a fairly basic grasph on pre-algebra, then you should be able to solve this.
Hope this helps!
Answer:
8
Step-by-step explanation:
Hi!
So there are two ways to do this, the second way is the easier way
First way:
We can use the Pythagorean Theorem.
If [tex]a^{2}+ b^{2}=c^{2}[/tex]
That means:
[tex]a^{2} = c^{2} - b^{2}[/tex]
Now we plug in the numbers
[tex]x^{2} = 10^{2} - 6^{2}[/tex]
[tex]x^{2} = 100 - 36[/tex]
[tex]x^{2} = 64[/tex]
[tex]x=\sqrt{64}[/tex]
[tex]x=8[/tex]
Second way:
We can use Pythagorean Triplets
We can use the 3,4,5 triplet
We can also put this in a ratio to help you visualize this
3y:4y:5y
Over here, you'll notice that if you make y = 2, then you get this
3(2):4(2):5(2)
Simplify
6:8:10
Well, 6 and 10 are given in this problem so that means that x has to be 8

Answer:
a) 7/12
b) 1/6
Step-by-step explanation:
(1)
Number greater than 5 include;
6, 7, 8, 9,10, 11, & 12
= 7
Probability of event = number of outcome ( total number of possible events )
= 7/ 12
(2)
Total number of possible events = 180 * 12
= 2160
Number of outcomes for;
Rolling a 3 = 1 * 120 / 2160 = 120/2160
Rolling a 9 = 1 * 120/2160 = 120/2160
Rolling a 11 = 1 * 120/2160 = 120/2160
120/2160 * 3
360/2160
= 1/6

What is the range of the function y = 4x - 7 when the domain is {-2, -1, 3}?
The range of the function is {-15, -11, 5}.
What is a function?A relation is a function if it has only One y-value for each x-value.
To find the range of the function, we need to substitute each value in the domain and evaluate the function.
When x = -2:
y = 4(-2) - 7 = -15
When x = -1:
y = 4(-1) - 7 = -11
When x = 3:
y = 4(3) - 7 = 5
Therefore, the range of the function is {-15, -11, 5}.
